Abstract

In one aspect the present invention is directed to mutant Neutrophil Gelatinase Associated Lipocalin (NGAL) proteins that have the ability to bind to siderophores, such as enterochelin, and to chelate and transport iron, and that are excreted in the urine. Such NGAL mutants, and complexes thereof with siderophores, can be used to clear excess iron from the body, for example in the treatment of iron overload. The NGAL mutants of the invention also have antibacterial activity and can be used in the treatment of bacterial infections, such as those of the urinary tract.
